Subject: Correct Times
So upon playing track 414-AAA TRACK-3 in the embedded player here on the site the correct times (relative to those posted by dave4455) are as follows:

Instruction to stir tanks: 2:32:20
Static burst: 2:33:55
Swigert declares they have a problem: 2:34:25

All times here are given with a few seconds of lead before the noted event occurs.

Subject: Amazing Collection!
Many thanks to John Stoll for uploading these priceless audio tracks. This collection of Apollo 13 tapes (and all the other missions he has uploaded) are a goldmine of information for people who have a genuine interest in Apollo and the US Space Program.

The printed transcripts help but there are numerous errors in them. Listening to the voices can not only correct these errors but also give an insight into the emotions going on at the time. This is especially true of Apollo 13.

For those interested 414-AAA TRACK-3 is the Air To Ground track for before and during the accident. This also contains the PAO commentary. I downloaded this track and many others and I can give a few time stamps as follows. These are given a second or two before the event:

2:51:20 - End of TV broadcast

2:58:24 - CAPCOM gives instruction to stir up Cryo tanks

3:00:20 - Static burst indicating the mishap in the Service Module occured

3:00:44 - Swigert declares they have a problem, which is repeated by Lovell about 10 seconds later.

787-AAI to 790-AAI is the Flight Loop. Gene Kranz is the Flight Director at the start and hands over to Glyn Lunney during 788-AAI.

Many thanks again John! A priceless collection.

Thanks to the laborer who made and uploaded these files. My impression of the astronauts trial seems to be uncommon even, well, Ive never ever heard anyone say it this way. Commander Lovell seemed bitter after the accident. Fred and Rusty seemed a little shocked but functioned well. Now mind I do not blame Jim Lovell, I believe I surley would have turned to self pity at my bad luck. Jim was sarcastic at times, before the biggest obsticles to survival had been licked. I say he was severley disappointed about his situation which means... he hadnt given failure much thought before launch. I would have expected that. Anders said that it was 1/3 they'd make it on the moon, 1/3 they wouldnt make it but get back and 1/3 death. I hold these to be about right given the complexity and newness of almost all of the technology. Those machines must have had some fine engineering in them because they all got back, even Apollo 13. Only because of the quality and the adaptability of the space crafts, did they get back. Charging the CSMs battery was one miracle way above some others. The big lithium canister adaptation was not clever at all but it's all documentaries talk about, how silly. That was a no brainer and the logical next step, a school boy would have figured that out. Above all I think is the skill of those 'Fly Boys'. Threading into the re-entry slot by hand and eye coordination with a burn from the still attached an wobbling LEM!?!?! This was the greatest of the miracles I think.

Subject: It would be better to scribe about content of the files
Well, well, well.
I loaded several files and found.
405-AAA_TRACK-1.mp3 and 406-AAA_TRACK-1.mp3 contain PAO announcements, voice of Capcom and crew and background sound.
405-AAA_TRACK-2.mp3 and 406-AAA_TRACK-2.mp3 contain only weak background sound.
405-AAA_TRACK-3.mp3 and 406-AAA_TRACK-3.mp3 contain PAO announcements, voice of Capcom and crew without background sound.
405-AAA_TRACK-4.mp3 and 406-AAA_TRACK-4.mp3 contain only background sound.
405-AAA_TRACK-5.mp3 and 406-AAA_TRACK-5.mp3 contain voice of Capcom and crew.
405-AAA_TRACK-6.mp3 and 406-AAA_TRACK-6.mp3 contain voice of ground personal, I cannot understand who exactly.
405-AAA_TRACK-7.mp3 and 406-AAA_TRACK-7.mp3 contain no sound.
Background sound and empty tracks would be interesting for historians but it would be better to publish announcement about contents of the files.

Subject: Apollo-13-Problem (recovered)
A great job, i am on it for hours, super team work, how they work the problem.

Definitely five stars, i would give ten.


Apollo-13-Problem did break off at about 35 minutes however if you did listen there was still audio only to fast in pitch and reversed, i did reverse that last part and pitched it down so that it did match with the first segment, then adjusted the DB level and this is the result, i had to upload it in MP3 because my upload speed is to low. With respect and thanks to John Stoll

You can find that recovered part here:

Subject: Apollo 13 - Flight director's loops
Hi John,

Good job on the transcriptions.

I'm listening to the flight directors loop tapes 787-AAI, 788-AAI, and 789-AAI. Very exciting stuff.

I am wondering, does the rest of the flight director's loop tapes for the rest of the mission exist? Also are there any of the flight controller loops too? This would be very interesting to hear from an engineering interest point of view. I know Sy Liebergot has published his tapes in a CD. Do any more exist it in the nasa archives?

Thanks again,

Subject: Noise on New File
A lot of noise on track 1 (the public release line), but track 3 appears to have the same recording - but without the noise!

I should have checked more recordings before giving a negative review!!!

Definitely five stars!

Subject: Missing files
I've come back to continue listing to the mission control audio files numbered 405-AAA through 428-AAA however they all seem to be gone and what's left are some flight director's loop stuff. Any idea where they are?

Subject: My two cents on the contents of audio track 795-AAB and 938-AAG.
Hi John

I agree that this track is a simulation and it takes place on St Patrick’s Day, March 17th, 1970 as they do reference St Patrick’s Day by name and the crew don’t want to miss their liberty. But from what I gather this simulation is with the Apollo 13 backup crew; CMDR: John W. Young, CMP: John L. "Jack" Swigert and LMP: Charles M. Duke, Jr and not the prime crew.

At approximately 02 min and 04 sec the audio picks with the debriefing from the simulation and later on someone will mention that the backup crew is on the line ready for the debriefing. At approximately 01 hour and 36 sec into the track the audio picks up toward the beginning of the simulation.

The Flight Director is Milt Windler which would make this the maroon team and the maroon team EECOM is John Aaron. Throughout the track you will hear the CAPCOM (sounds like Joe Kerwin) call out to the command module simulator as “Apollo 13” and often refer to the crew by name John, Jack or Charlie.

Track 938-AAG is Apollo 11, Neil and Buzz prepping for their EVA..

Subject: 795-AAB
Moepower: You are correct that the first part of this file is a recording of a simulation. It then goes back into the actual flight recodings.

At the end of the simulation portion, they discuss "liberty" and that it was St. Patricks this exercise was evidently in prep for the actual flight and was conducted on March 17, 1970.

These are great. I hope they are restored, soon. Hopefully, there will be more descriptions of each file.

Subject: Mission Audio Files
Thanks for contacting about the mission audio files! The Apollo 13 mission tapes are on 7-track, 1/4 inch. The tapes run about six hours apiece. I originally digitized this mission about six years ago, at a time when I didn't have enough parallel processing (and hard drive space) to capture all seven tracks at once. I have that capability now, so I am re-digitizing the original tapes, this time all seven tracks...
Thanks again for the contact! Should have some content here in a few weeks or so...

Subject: Apollo 13 - Where are the files?
Hi all

I was just wondering where the audio files have gone to that were here on this page?? The mission specific audio files were available but now dont seem to be....or am I missing something?

With regards

Subject: Air to Ground zipfiles do NOT contain Apollo 13 audio

First, many many thanks for making this fantastic resource available.

Second: files and contain Shuttle/ISS soundbites. Haven't listened to each and every file inside the archive, but every one I did listen to was Shuttle related.

Third: I had a hard time downloading these files. Many many times the downloads would end in mid-stream, because the server stopped transmitting. I analysed for network problems on my side (I'm an IT engineer...) but I haven't found any. Anyone else had the same experience with downloads from ?

Fourth: any chance the 4 missing files (as indicated by Mr. Larry's post on 8 March 2012) can/will be added anytime soon?

Five: is there any way in which I can help curate this collection?

Best regards, EJ Bartelds, The Netherlands
